Summary Introduction
To review:
The
Figure 1: Distance between different genes (in map units).
Introduction:
The chromosomes undergo crossing over during meiosis, during which the genetic material from both the parents gets exchanged. During a cross-over a new type of phenotype is formed, representing recombinants that are different from either parent.

What is a reciprocal cross? Suppose that a gene is found as a wildtype (functional) allele and a recessive mutant (nonfunctional)allele. What would be the expected outcomes of reciprocal crossesif a true-breeding normal individual was crossed to a true-breedingindividual carrying the mutant allele? What would be the results ifthe gene is maternally inherited?
A different walnut rooster was crossed to a rose hen, and all the progeny were walnut. What are the possible genotypes of the parents?
A cross was made between a white male dog and two different blackfemales. The first female gave birth to eight black pups, and the second female gave birth to four white and three black pups. What arethe likely genotypes of the male parent and the two female parents?Explain whether you are uncertain about any of the genotypes

What are the likely genotypes of the parents?arrow_forwardIn the same cross as question #1, what fraction of the offspring will have their father's genotype for both traits?arrow_forward
- in a test cross, a pure-breeding plant is crossed with a plant suspected to be heterozygous (Aa). what is the gentype of the pure-breeding plantarrow_forwardImagine you have two pure-breeding lines of canaries,one with yellow feathers and the other with brownfeathers. In crosses between these two strains, yellowfemale × brown male gives only brown sons anddaughters, while brown female × yellow male givesonly brown sons and yellow daughters. Propose ahypothesis to explain these resultsarrow_forwardThe cross between a female white giraffe and a pigmented male resulted in white offspring. What is the genotype of the father? Draw the test cross.arrow_forward
- Assuming a typical monohybrid cross in which one allele is completely dominant to the other, what ratio is expected if the F1's are crossed?arrow_forwardSuppose a student performs a three-point test cross with mice involving mouse genes T, V and D. If the most abundant classes of progeny are TvD and tVd and the rarest classes are tvd and TVD which gene is in the middle and what is the genotype of each mouse involved in the cross?arrow_forwardWhen a white guinea pig is crossed to a yellow guinea pig, all the progeny are cream colored. From a cross of two such F1’s, the F2 showed 32 white, 66 cream, and 30 yellow guinea pigs. How is this trait inherited?arrow_forward
- Following a cross between two, dihybrid, heterozygous individuals, what fraction of the offspring are predicted to have a genotype that is heterozygous for both genes?arrow_forwardin the the dihybrid cross of Mendel how many genotype and phenotype?arrow_forwardSuppose you identify a new gene in mice. One of its alleles specifies white fur, another specifies brown. You want to see if these alleles are inherited in a Mendelian pattern, or with incomplete dominance. What crosses would give you the answer? Explain.arrow_forward
